The Bible has a lot to say about love, but it also has a lot to say about hatred and selfishness. The price for hatred and selfishness is eternal punishment in hell. If you are someone who hates others you have earned yourself a place in hell for eternity.
But God will forgive you of your sin if you repent and believe in His Son Jesus Christ. God can change you inside out and replace your hatred for others with love. Once this transformation occurs you will know that God has heard your cry of repentance and has forgiven you of your sins so you will not go to hell.
“God is love. Whoever lives in love lives in God, and God in them. 17 This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus.” (I John 4:16b-17 NIV)
